New material to revolutionize water proofing
Scientists at The Australian National University (ANU) have developed a new spray-on material with a remarkable ability to repel water. The new protective coating could eventually be used to waterproof mobile phones, prevent ice from forming on airplanes or protect boat hulls from corroding.

Stealth pig cells may hold the key to treating diabetes in humans
University of Alabama at Birmingham researchers are exploring ways to wrap pig tissue with a protective coating to ultimately fight diabetes in humans. The nano-thin bilayers of protective material are meant to deter or prevent immune rejection. The ultimate goal: transplant insulin-producing cell-clusters from pigs into humans to treat Type 1 diabetes.

UAlberta mechanical engineering in hot pursuit of creeping bacteria
The growth of bacterial biofilm is problematic when you think of all the liquid flowing through all those miles of tubing at your local hospital or Medi-Centre. The movement of bacteria with flow can lead to the spread of infection. Mechanical engineering professor Aloke Kumar's lab set out to study the formation of the filaments, as well as the conditions under which they begin to break down and finally break off.

Breakthrough in materials science: Kiel research team can bond metals with nearly all surfaces
How metals can be used depends particularly on the characteristics of their surfaces. A research team at Kiel University has discovered how they can change the surface properties without affecting the mechanical stability of the metals or changing the metal characteristics themselves. This fundamentally new method is based on using an electrochemical etching process, in which the uppermost layer of a metal is roughened on a micrometer scale in a tightly controlled manner.

Tooth decay -- drilling down to the nanoscale
With one in two Australian children reported to have tooth decay in their permanent teeth by age 12, researchers from the University of Sydney believe they have identified some nanoscale elements that govern the behavior of our teeth. Material and structures engineers worked with dentists and bioengineers to map the exact composition and structure of tooth enamel at the atomic scale.

Nature Materials
Researchers design solids that control heat with spinning superatoms
Superatom crystals are periodic arrangements of C60 fullerenes and similarly sized inorganic molecular clusters. There are two nearly identical formations, one with rotating (i.e. orientationally disordered) C60s and low conductivity, and one with fixed C60s and high thermal conductivity. Superatom crystals represent a new class of materials with potential for applications in sustainable energy generation, energy storage, and nanoelectronics. Additional research could lead to controlling rotational disorder in new kinds of thermal switches and transistors.

Nanotechnology supports treatment of malignant melanoma
Changes in the genetic make-up of tissue samples can be detected quickly and easily using a new method based on nanotechnology. This report researchers from the Swiss Nanoscience Institute, the University of Basel and the University Hospital Basel in first clinical tests with genetic mutations in patients with malignant melanoma. The journal Nano Letters has published the study.

Location matters in the self-assembly of nanoclusters
Scientists at Iowa State University have developed a new formulation that helps to explain the self-assembly of atoms into nanoclusters and to advance the scientific understanding of related nanotechnologies. Their research offers a theoretical framework to explain the relationship between the distribution of 'capture zones,' the regions that surround the nanoscale 'islands' formed by deposition on surfaces, and the underlying nucleation or formation process.

Super-resolution microscope builds 3-D images by mapping negative space
Scientists have demonstrated a method for making 3-D images of structures in biological material under natural conditions at a much higher resolution than other existing methods. The method may help shed light on how cells communicate with one another and provide important insights for engineers working to develop artificial organs such as skin or heart tissue.

For first time, carbon nanotube transistors outperform silicon
For decades, scientists have tried to harness the unique properties of carbon nanotubes to create high-performance electronics that are faster or consume less power. Now, for the first time, University of Wisconsin-Madison materials engineers have created carbon nanotube transistors that outperform state-of-the-art silicon transistors.

'Materials that compute' advances as Pitt engineers demonstrate pattern recognition
The potential to develop 'materials that compute' has taken another leap at the University of Pittsburgh's Swanson School of Engineering, where researchers for the first time have demonstrated that the material can be designed to recognize simple patterns. This responsive, hybrid material, powered by its own chemical reactions, could one day be integrated into clothing and used to monitor the human body, or developed as a skin for 'squishy' robots.

Pitt chemical engineer receives NSF grant to study self-assembly of large-scale particles
'Fabricating the self-assembly of larger particles had been done a handful of times before we started trying it, but we've pushed the possibilities a lot further,' said McCarthy. 'Other researchers noticed the phenomenon occurring empirically, but we are trying to formalize it. We are working with particles that are at least 100 times bigger than anything that has been done before.'

Customer publishes performance evaluation of first commercial mini-synchrotron
A team from the Technical University Munich (TUM) recently reported an independent analysis of the operation of the Munich Compact Light Source (MuCLS) in the Sept. 2016 issue of the Journal of Synchrotron Radiation. The MuCLS is the first commercial installation of a miniature synchrotron developed and manufactured by Lyncean Technologies, Inc. of Fremont, CA. It is designed to fill the gap in X-ray performance between conventional X-ray sources and stadium-sized synchrotron radiation X-ray facilities.
